Girl, you definately have a circular pattern going on with this guy. The first step in healing this situation is to completely end it with him. In order to start over fresh it has to be ended. With you talking and having sex as often as you are the wounds of the past have yet to heal. You need to completely cut him out for a period of time. It doesn't have to be indefinate and it doesn't even have to be a long period of time, but you both need a time out. Let's say maybe 1 month of zero contact, what that gives you is one month to see where you stand personally and how he is going to behave through out that time period. If he truly loves you, than he will re-discover that after realizing that he was temporarly or perminentaly lost you. It is that old saying "you never know what you have until it's gone". It will work for both of you. If after a week or so you start to think about him less or he falls into another relationship then that should tell you that it isn't meant to be. If after that 30 days, you have never stopped thinking of him and he has been completely single and only thought of you then you know you have a chance at something real with him. I am not saying that a month is the right amount of time. For some people they need more time and space and others realize things after a few days. The main thing is to clear both of your heads and find out where you truly stand. Sometimes we get used to what is normal or comfortable and we tend to go back to it just to feel safe. Don't make that mistake. Don't be his safe zone.
